Recovering ASP.NET after an IIS crash

Your Internet Information Server crashed, and you reinstalled it. Now, how to re install ASP.NET so that IIS can load and execute aspx pages? There is a tiny tool aspnet_regiis.exe in your Microsoft.NET system folder (e.g, at C:\WINDOWS\Microsoft.NET\Framework\vx.x.xx). Execute aspnet_regiis.exe -i (don't foget the -i switch) in the command prompt.
